Abstract: The text summarizes the researches and practices of energy dissipation measures in hydroelectric power station,introduces different energy dissipation measures in different discharges and its characteristics.It may be a reference to the design in engineering.But it must be pointed out that in practice,because of the different landforms,geological conditions,different dam figures and hydrological conditions,energy dissipation measures and its disposal are different,too.In order to get the best results,it must be tested on model experiments,and if the situation permits,it can be tested on prototype.
